April 2021 TechTIPS Page 1 of 8 Subaru Service and Technical Support Line Newsletter ©2021 Subaru of America, Inc. All rights reserved. 01 QMR of the Month We are pleased to announce this month’s QMR of the Month Winner: Leo Gilmore from Ruge’s Subaru in Rhinebeck, NY Another Subaru “first” occurred this month when Leo Gilmore’s QMR was selected from February’s submissions making him our first back-to-back winner! This is quite an accomplishment. The reports selected to be finalists each month are proof more and more Technicians are stepping up their game as evidenced by the quality of QMRs being submitted. THANK YOU! Quality reports like these are invaluable in helping with our initiatives directed at enhancing vehicle quality. Leo’s report outlined the diagnosis and repair of an electrical issue on a brand-new 2021 Outback with just 8 miles on it and multiple warning lamps illuminated in the combination meter. An initial All Systems scan revealed several DTCs for communication failures between EyeSight and various vehicle systems. He began checking into the CAN system by performing various resistance checks between sections of the instrument panel harness. Once Leo’s testing revealed an open circuit, he proceeded to use the split-half technique to help isolate the trouble source. Reviewing the wiring diagram again showed 2 splices in the harness between connector i88 at the Central Gateway module and instrument panel harness connector i52. This section of the harness is located behind the BIU. With his DVOM connected, Leo was able to manipulate the suspected location of the splices and induce changes to the resistance values. Replacing the faulty instrument panel harness restored normal operation. As he has done previously, his QMR contained a PowerPoint® presentation which included a short video along with numerous pictures, a detailed progression of the diagnosis and the related testing results. In appreciation for going the extra mile and sharing his experience with us, Leo will be receiving the following from his Field Service Engineer: $500.00 Snap-On gift card SUBARU TECHLINE HOLIDAYS & HOURS OF OPERATION Memorial Day: (Closed) Monday, May 31, 2021 Mon. – Thurs. 8:30AM – 7:30PM EST Friday 10:30AM – 5:00PM EST Saturday 9:00AM – 3:00PM EST Articles Contained in this Issue Click on a title below to jump to the article.

April 2021 TechTIPS Page 3 of 8 Continued on the next page This series features TechTIPS articles frequently referred to by Techline. This month’s feature is from June 2019. 01 Vibration After Transmission or Engine Removal Techline has received increasing concerns of vibration after transmission or engine removal. Multiple cases have been identified where the vibration has been traced back to the snout of the torque converter being broken. This can happen if the torque converter holder tool is not used. When removing an engine or transmission the component needs to be released as straight as possible without any rocking or pitching. The photo above shows the nose of the torque converter is broken off and remaining in the crankshaft. Also note, there is no torque converter holder tool installed to the transmission. Torque converter with broken nose. During component removal it is imperative to follow all steps of the procedure as outlined in the Service Manual. In addition, always confirm both dowel pins are installed in the engine block before engine reinstallation to insure proper engine to transmission alignment. April 2021 TechTIPS Page 4 of 8 Continued on the next page 01 Dash Camera Etiquette – Behave like you’re being watched With insurance companies offering discounts for safe driving, customers interest in recording their track sessions, enthusiasts recording meetups, and various other reasons, the use of in car video and audio recording devices is becoming more commonplace. Many of these recording devices are designed to start audio and video recording automatically when the vehicle ignition is turned to the on position and can record for several minutes after the ignition is turned off. While this offers a level of convenience for the end user, it can, and has, caught unwitting technicians less than professional behavior on film for the customer to see. It’s also worth noting that the customer may get to see your workspace, which can leave a lasting impression about the quality of your service department. As a representative of your retailer, and Subaru of America, it’s vital that a level of professionalism and cleanliness when interacting with customers and their vehicles is maintained, because you never know when someone may be watching. 03 Ascent or Legacy/Outback 2.4L Binding When Turning Basic Diagnosis Overview If you encounter an Ascent or Legacy/Outback 2.4L Turbo equipped with TR690HRC CVT where the customer is reporting a binding or judder condition when turning, this article will provide some guidance on how to address the condition quickly and efficiently. Start by duplicating the condition via road test or in empty parking lot NOTE: Always be sure X-Mode is switched OFF If the vehicle has very low mileage see if the condition is resolved by performing transfer clutch breakin procedure. Drive the vehicle at very low speed (3 mph) in an open and empty parking lot through a series of tight circles to the left and to the right with the steering wheel at full lock in that direction while lightly accelerating and decelerating. Complete at least 10 turns in each direction. Then road test and see if the condition continues after allowing the CVT to return to normal operating temperature. Repeat an additional time if some improvement is felt but more is needed. If this does not resolve the condition, continue the inspection process. Once duplicated, inspect the vehicle’s tires. The tire circumference must be confirmed. As little as a quarter inch (1/4”) difference in rolling circumference can result in binding. Be sure all tires match in terms of brand and type as even tires from the same brand listed as the same size can have some variation in circumference. As example an Ascent with factory Falken Ziex tires and one or two Falken WildPeak replacement tires of the same size could experience a binding condition. Always check each tire carefully as you may also encounter a case where all four tires are the same brand and type but one or more may be of a slightly different size. Next connect the SDS Notebook and DSTi and check for any DTCs. Diagnose any DTCs found to eliminate them as a factor. Then put the CVT into Front Wheel Drive mode. In this mode the duty solenoid for the All Wheel Drive is turned off. This is achieved using the Transmission Control Module Settings in Work Support. Once activated drive the vehicle and look for any change in the condition. If the condition is no longer present this would indicate a possible concern with the AWD system transfer clutches which are repairable and do not require a CVT replacement. April 2021 TechTIPS Page 5 of 8 Continued on the next page Ascent or Legacy/Outback 2.4L Binding When Turning Basic Diagnosis Overview (CONTINUED) 03 The next step would be to try changing the CVT fluid. It is possible that during break-in some burnishing of the transfer clutch plates may have occurred in which case a CVT fluid change may be all that is required to alleviate the condition. If that does not resolve the condition, the next step would be to remove the extension housing and inspect the end play and clearance as well as the condition of the drive and driven plates and overall condition of the seals, hub and housing. Refer to the applicable Service Manual for full details of the inspection and proper setup of the transfer clutch assembly. Note that following this repair some parking lot break-in may be required but should not be extensive. 14 Special Tools – Denso USB Cable Techline has received an increase of concerns from technicians not being able to perform basic tasks when using the SSM4. This condition has been identified and is directly related to the use of aftermarket USB cables connected from the DST-i box to the SSM/Toughbook. Techline would like to remind everyone to always use OE Denso USB Cable equipment when diagnosing or updating Flashwrite2 PAK files with the SSM/Toughbook. Reports of no communication with control modules, software updates crashing, and error messages being displayed has resulted in unrecoverable data leading to unnecessary control module replacement. There is no way to determine if an aftermarket cable will be able to perform all the tasks that the SSM4 or Flashwrite2 requires. Please be sure that replacements for damaged USB cables are ordered directly through SubaruDT. com. Contact Subaru Dealer Technologies to order genuine Denso parts. Pricing is available in the RISE hyperlink under Service Operations & Technical in Subarunet.com. As a final note, be sure to inspect the physical port on the DST-i and Toughbook for damage before use.
